' PORTABLE ELEVATOR v Filed March 5, 1927 3 Sheets-Sheetv 2 6192, 1641847 Sept G. c.-GooD ET AL 'PORTABLE ELEVATOR Filed March s; 1927 s shets-sheet 5 vifi tor 11 at 28, and extends vertically, over the sheave26, then downward adjacent one of the upright members 10 and around the guide sheave 29, and thereafter is operatively connected to any desired form of hoisting engine located adjacent the base platform 1.

The head member comprises a air of channel beams 30, secured toget ier by means of bolts 31 and provided adjacent their respective ends with sleeve segments 32, 32, each of which is integrally connecter to one of the channel beams 30, 30, as shown in Figs. 4 and 5. The vsleeve segments 32, 32 engage the upright members 10, thereby preventing the said upright members from spreading relative to each other.

p The sheave 26 is rotatably mounted on a shaft 33 y'secured inone endo a yoke. member 34 which extends over one of the channel beams 30 and is secured thereto by means of a bolt 35, as shown in Figs. 4 and 5. The openings between the outer parallel vertical edges of the sleeve segments 32, 32 permit the head member 25 to be mov-ed verr tically along the upright members 10, 10 Vpast the angle bar projections 7, 7, and a split ring 36 is provided on each of the -upright members l0 under each of the respective ends of the head member 25. The rings 36 are each provided With a slot 37 which is adapted to Vpermit the said ring to be moved vertically on the respective upright member 10,V past the angle bar projections 7, after which it is adapted to be rotated horizontally on the said upright member 10 until the slot 37 is moved out of alignment With the leg 8 of the angle bar section 7, thus the. said ring is prevented from moving downward 'on the upright member 10, and-the respective ends of the said member 25 bear en the upper surfaces of the pair of rings 36, which supports the head member 25 in place. i

The previously mentioned strips 1.2 are secured to the legs 9 of the .respect-ive bar lsection 7 by means ol' bolts 38, 38, and are adapted to receive socket members 40, each of which comprises a rect-angular trame having studs 41, 41 integrally connected to one of its faces and extending to each side oft the vertical strip 12. Strap members42, 4.2 eX- tend between each of the pairs of studs 41, 41 at the side of the strip .12 opposite to that engaged by the .rectangular frame 40. The

` studs 41 are provided with nuts 43 by means of which the Y rectangular frames may be rigidly clamped to the verticalst-rips 1.2.

In o eration, a wall is constructed to a height. conveniently reached from the ground level y, alter Which the base platform 1 is positioned adjacent the Wall so constructed. The first tube sections 5, 5 are then positioned in the foot pla-tes 4, 4 of the base. platform and thehbrace members 13, N13 set in position. The elevator cage 11 is preferably attached to the lower sections 5 when the said sections are set in place, or the said elevator cage may be placed on the tube sections 5` after. they are set in position. The rings 36 and head member 25 may then be placed in position on the tube sections 5, 5. Additional tube sections 5, 5 are then placed on these first sections, and the strips .12 bolted in place to prevent the vseveral superposed sections Jrrom coming apart. yThe head 25 may then be movedver- Ytically along-'the upright members 10, 10,

50 may be slipped into the said rectangular trame members 40 and their opposite ends permitted to rest upon the top o l the Wall as shown in Fig. 2. A suitable platform 51 may then be constructed on the beams 50 in such a position as to permit the platform 11a of the elevator cage 11 to be raised to a position in alignment with .the platform 51. The elevator is now in condition for operation. The building material may be loaded onto the platform 11a ofthe elevator cage and raised to the level oit theplattorm 51 in the usual manner and for the usual purposes.

The head member ties theupper ends lll() oit the upright members l0, 10 together and l prevents the spreading voi 'these saidV ineinbers. The shoes 20, 20 of the elevator, due Vto the Yfact that theyengage' the tube sections 5 over the greater vpart ol their circumference, prevent thespreading. ofthe uprightl members 10 atv points intermediate the base plattform 1 andthe head member 25, as theelevator 11 is moved up and' down the elevator shaft.;Y As the building of the Wall ir progr'esse-s, additional tube Vsections 5 may be added to the upper ends of the upright members 10, .l0 and the strips 12 lileivise extended rtatie these members together, additionaltrame members 4G being placed on the additional strip sections 12 and beams 50 beingplaced in these additional frame members and resting npon'lthe ivallsection as above described.V The head member 25, upon slacking;y of the cable, 27, may be raised to thenext desired height and locked thereinby the rings rldli'isel'ieiation is repeated Without-further br-acing'ct the upright members lO up to a point'adapteditor use construction of a tivo and onehalf story building. y Y .p

It a building of greaterv heightv is 'to be constructed, the upright members 10 may llU be braced to the building under construction by any formof brace members attached Vto theupright strips l2 in the form of string .ers having one end secured to the building and the opposite end nailed or otherwise setiveL rrloireplace the hod carrier with the old type of yWooden, elevator shaft :Would not better thecondition due to the expense connected Wit-li the erection of such'a device, the material employed in such construction being practically destroyed andy unfit for further use afterthe buildingivas completed.`

lith our improved typeof portable elevator,` this cost of material is eliminated due to the'fact that thexcomponent parts'of our construction maybe successively used Without injury. The time required for' erecting the elevator considerably reduces the construction cost; thus thefcontactor may einploy this type of device With a'considerable saving of time and'money; and thusnialre the constructionfof arelatively small building, usingtlie cement block, profitable. 1We claim: -fg l i v f v j l.
